In pooled analysis, NBI is comparable to chromoendoscopy in their sensitivity and specificity in the diagnosis of malignant colorectal adenomas [4]. Unfortunately, the use of NBI has not been shown to conclusively improve rate of colorectal adenoma detection. Two of 3 randomized trials that compared WLE to NBI showed a higher adenoma detection rate with the use of NBI [5, 6]. In a study by Rex et al., the rate was however similar with either modality. In a pooled analysis, NBI was only marginally better than WLE [7].
